Overview
Calnexin a calcium-binding protein of the calreticulin family. A type I membrane protein of the endoplasmic reticulum .Interacts with newly synthesized glycoproteins in the endoplasmic reticulum. May act in assisting protein assembly and/or in the retention within the ER of unassembled protein subunits. It seems to play a major role in the quality control apparatus of the ER by the retention of incorrectly folded proteins. Note: This description may include information from UniProtKB.
Protein type: Calcium-binding protein; Endoplasmic reticulum; Membrane protein, integral; Motility/polarity/chemotaxis
Cellular Component: dendrite cytoplasm; endoplasmic reticulum membrane; protein complex; cell soma; membrane; endoplasmic reticulum; endoplasmic reticulum lumen; axon; dendritic spine; melanosome; ribosome
Molecular Function: ionotropic glutamate receptor binding; protein binding; unfolded protein binding; apolipoprotein binding; calcium ion binding; glycoprotein binding
Biological Process: antigen processing and presentation of peptide antigen via MHC class I; cellular protein metabolic process; protein folding; synaptic vesicle endocytosis; protein secretion; antigen processing and presentation of exogenous peptide antigen via MHC class II; protein amino acid N-linked glycosylation via asparagine; post-translational protein modification; aging
